Definitions

  • R is a monovalent aliphatic hydrocarbon radical, saturated or unsaturated, of 8 to 20 carbon atoms, preferably of 12 to 18 carbon atoms;
  • R 1 , R 2 , R 3 may be identical or different and each represents a lower alkyl radical of at most 4 carbon atoms, or an aryl radical.
  • R is the lauryl, myristyl, cetyl or aleyl radical, and R 1 , R 2 R 3 each designate a methyl, ethyl, propyl, isopropyl, phenyl or benzyl radical.
  • the quaternary ammonium salts of malic acid may be prepared by reaction of maleic acid with the corresponding hydroxide of the quaternary ammonium salt: ##EQU3## in aqueous medium in the presence of ethanol or isopropanol.
  • the corresponding hydroxide of the quaternary ammonium salt may be prepared in situ by reaction of the corresponding halide of the quaternary ammonium salt with an excess of silver hydroxide, preferably freshly prepared.
  • the new quaternary ammonium salts of malic acid of this invention are especially useful in cosmetics. It is known that malic acid is one of the fundamental factors in cellular metabolism, and as such it presents considerable interest in cosmetics, especially in the manufacture of cleansing creams.
  • malic acid cannot be used in the free state or neutral state without certain precautions, because it interferes as an electrolyte and, in reducing the stability of the emulsions, it can lead to break-up of the emulsion.
  • the electric conductivity of the aqueous phase of the emulsion increases, the electrostatic charges on the particles of the oily phase in suspension are reduced. This causes a lowering of the forces of repulsion which may thus become less than the Van der Waals forces of attraction, and this inevitably leads to the break-up of the emulsion.
  • fat-soluble esters of malic acid be used in place of the said acid to achieve a better intracellular penetration of malic ion. Nevertheless, these esters have a tendency to hydrolyze in aqueous solution, which affects the stability of cosmetic emulsions. Moreover, they are not surface-active, and are neither bactericidal nor anti-fungicidal.
  • the quaternary ammonium salts of malic acid of this invention are particularly valuable for the care of the skin in general, and especially in cosmetics, for the following reasons:
  • This malic ion penetrates the skin rapidly through the sebum, thanks to the lipophilic quaternary ammonium ion to which it is in polarly bonded.
  • these substances being water-soluble, may be used in aqueous solution, for example in hair lotions.
  • Silver nitrate (600 g) is dissolved in purified water (2.5 liters).
  • the pH of an aqueous solution to 1/5 strength should be near 6.
  • the mixture is concentrated to about 3 liters by distillation of ethanol, then evaporated to dryness under vacuum (60°C, 15 mm Hg).
  • the cetyltrimethylammonium malate is obtained as a white mass of waxy consistency, soluble in water and alcohols, insoluble in petroleum ether, benzene and cyclohexane.
  • composition cetylmethylammonium ion: 81.17%
  • Absolute ethanol was added to break up the foam which would make concentration impossible; ethanol may be replaced by smaller quantities (about 1 liter) of isopropanol.
  • silver hydroxide may be avoided by using anion exchangers of the polystyrene/quaternary ammonium type (for example, Amberlite I R A 400) to fix the chlorine.
  • anion exchangers of the polystyrene/quaternary ammonium type for example, Amberlite I R A 400
  • cetyltrimethylammonium malate is applied in aqueous solution (25% w/w).
  • the pH of the solution is near 6.
  • test mixture above is boiled vigorously. A rancid odor, characteristic of fatty alcohols, develops.
  • the sumagent alcohol is separated: M.P. 49°C.
  • the mixture is stirred until all is dissolved (about 30 minutes), and the volume made up to 1000 ml with water.
  • VS blue (0.2 mg/ml, 5 ml)
  • VS blue (CI 42045) is the sodium salt of [[ ⁇ -[p-(dimethylamino)phenyl]-disulphobenzylidene-2,4]-4cyclohexadiene-2.5-ylidine-1]diethylammonium) ##SPC1##
  • the upper solvent phase is colored turquoise blue, whereas there is almost no coloration in a control solution containing no cetyltrimethylammonium malate.
  • cetyltrimethylammonium malate solutions may be titrated by potentiometry in an anhydrous acetic medium as follows:
  • malate solution (approx. 1 g) weighed to an accuracy of 0.1 mg.
  • Anhydrous acetic acid (R) 80 ml is added, and the solution is concentrated at atmospheric pressure down to about 40 ml to remove water by azeotropy.
  • V volume (ml) of perchloric acid consumed
  • M molecular weight of cetyltrimethylammonium malate: 701.25
  • Example 2 The procedure followed is that of Example 1, but using maleic acid (227.6 g) and an aqueous solution of lauryltrimethylammonium chloride (25 %, 3.576 g).
  • Lauryltrimethylammonium malate is obtained as a white mass of waxy consistency, fragrant, soft, soluble in water, methanol and ethanol.
  • composition lauryltrimethylammonium ion 77.60%
  • Lauryltrimethylammonium malate is supplied in aqueous solution (25% w/w).
  • This solution is limpid, colorless to light yellow, almost odorless, has a very bitter taste and froths copiously on agitation.
  • the pH of the solution is near 6.
  • reaction 2 where the suragent alcohol separated has a melting point of 24°C.
  • Example 2 The procedure followed is that of Example 1, but using maleic acid (162.5 g) and an aqueous solution of cetyldimethylbenzylammonium chloride (25%, 3.696 g).
  • Cetyldimethylbenzulammonium malate is obtained as a white powder of waxy consistency, soluble in water and alcohols.
  • composition cetyldimethylbenzylammonium ion 84.0%
  • Cetyldimethylbenzylammonium malate is supplied in aqueous solution (25% w/w). This solution is limpid, colorless to light yellow, almost odorless, has a very bitter taste and froths copiously on agitation. The pH of the solution is near 6.
  • a methylene blue iodomercurate reagent paper Into an aqueous solution of cetyldimethylammonium malate, is placed a methylene blue iodomercurate reagent paper. A displacement of the iodomercurate ion is observed and the blue coloration passes into the solution.
  • Example 2 The procedure followed is that of Example 1, but using maleic acid (188 g) and an aqueous solution of lauryldimethylbenzylammonium chloride (25%, 3.646 g).
  • Lauryldimethylbenzylammonium malate is obtained as a white mass of waxy consistency, soluble in water and alcohols.
  • the lauryldimethylbenzyl ammonium chloride is supplied in aqueous solution (25% w/w). This solution is limpid, colorless to light yellow, almost odorless, has a very bitter taste and froths copiously on agitation.
  • the pH of the solution is near 6.
  • a methylene blue iodomercurate reagent paper Into an aqueous solution of lauryldimethylbenzylammonium malate is placed a methylene blue iodomercurate reagent paper. A displacement of the iodomercurate anion is observed and the blue coloration passes into the solution.
